Applioatlon filed June 27, 1921.

To all wlwm it may concern:

Be it known that I, GUSTAV'E BLUEMEL, a citizen of German Austria, residin at T0- ledo, in the county of Lucas and tate' of Ohio, have invented certain new and useful Improvements in Heaters and Kindlers, of which the following is a specification.

This invention relates to certain new and useful improvements in apparatus for mixing air and a fluid such as crude oil and for supplying the same under pressure for various uses.

The invention is particularly designed to furnish a portable apparatus of simple and eflicient construction for use in setting tires, straightening frames and heating metal for many other purposes, also for kindling fires in locomotives, and in many other ways.

One of the primary objects of the invention is to provide a valve of simple construction which can be easily made and operated to control the length and intensity of the flame and adapt the apparatus for a variety of diflerent uses.

And further objects of the invention are to control the mixture of air and fluid by the operation of a single valve so that a desired mixture may be constantly maintained adapted to the particular work then being performed; to thoroughly mix the air and fluid in the valve and deliver the same in a thoroughly atomized condition to the burner; and to provide simple means for cleaning the valve at the conclusion of the operation.

In the accompanying drawings I have illustrated the invention in a sectional view and referring thereto 1 is a fluid tank preferably mounted on wheels so that it can be easily transportedfrom place to place. A valve body designated generally 2 is secured in the top of the tank and it is provided with an air chamber 3 and a mixing chamber 4. f

An air line 5 is connected at 6 to the valve body and communicates through a passage 7 with the air chamber; A passage 8 connects the air chamber with the tank. A stem 9 provided with a hand wheel 10 on its outerend threadedly engages the valve body and carries a double cone valve 11 which engages an opening 12 in a partition 12 between the air chamber and the mixing chamher and also a shoulder 13 at the other end of the air chamber. The wall of the openadjacent the air chamber forms a seat Serial Nb. 480,680.

passage 14. A delivery hose 20 is connected to the valve body and communicates through a passage 21 with the mixing chamber 4. This delivery hose is preferably connected to one end of a metal pipe which carries on its other end a suitable burner, the pipe being employed for handling the burner in actual use and directing the flame as desired.

When the air valve 11 is seated against the shoulder 13 the air supply will be cut oil. To start the apparatus in operation, the fluid valve 18 remaining open, the air valve is moved forward from its seat 13 to its seat in the opening 12 thereby admitting air pressure from a suitable source of supply through the pipe 5, the passage 7, the air chamber .3, and the passage 8 to the tank. This pressure soon forces the fluid up through the pipe 15 and the passage 14 into the mixin chamber 4, and as soon as this flow is well started the air valve 11 is-withdrawn from its seat in the opening 12 and allowed to remain between this seat and the seat 13 so that the air may flow through the opening 12 directly into the mixing chamber where the tank fluid is thoroughly atomized and carried out through the delivery hose to the burner. The area of the opening 12 is greater than the area of the opening 21 and by adjusting the valve ll'different degrees of pressure may be established in the air chamber 3 and the mixing chamber 4 so that a greater or less quantity of fluid will be orced up into the mixing chamber.

The fluid valve 18 is employed for controlling the amount of oil used. When the operation is completed the fluid valve 18 is closed and the air is permitted to flow freely through the opening 12 and the mixing chamber to blow out surplus oil which may remain therein and in the delivery hose and burner.

My invention provides an apparatus of simple construction which can be easily manufactured and assembled at comparafor convenient operation so that the length and intensityof the flame can be easily and efiiciently controlled. The apparatus is very useful around railway shops and manufac- I turing plants because of its portability and because it can be utilized for quickl applying an intense heat for bending an repairing metal parts. It can also be used around shops and plants for man other purposes and it may also be used or kindling fires in locomotives.

I but. I may use any equivalent therefor and It is customary to use crude oil in the tank also any equivalent for the air premure heretofore described.

I have shown the valve body made up of three parts threadedly engaged as. a convenient method of manufacture but I reserve the right to make the valve body otherwise and to make other changes in the form, construction and arrangement of parts which 7 fairly fall within the scope of the following claims:

I claim:

1. The combination with a fluid supply tank, of a valve connected with the tank and with a source of compressed air supply,

- said valve comprising a body having an air air chamber for closing said air supply communication or said direct communication. 2. The combination with a fluid supply tank, of a valve connected with the tank and with a source of compressed air supply,

said valve comprising a bed having an air chamber communicating wit the air supply and also with the tank, a mixing chamber communicating with the tank and having a delivery outlet, a partition between said chambers and having an opening therein,

and a valve operating in the air chamber adapted to beseatedin said opening to di rect theflow of air through the air chamber into the tank, and adapted to be unseated to permit the flow of air directly from the air chamber into the mixing chamber.

3. The combinationv with a fluid supply I tank, of a valve connected with the tank and with a source of compressed air supply said valve comprisin a body having an air c amber communicating with the aim supply and with the tank, a mixing chamber communicating with the tank and having a delivery outlet, a communicating opening between the air chamber and the mixing chamber, and a valve in said air chamber adapted to be operated in one direction to close the air supply to the'mixing chamber and in the other direction to close the opening between the air chamber and the mixing chamber.

4. The combination with a fluid supply tank, of a valve connected with the tank and with a source of compressed 'air supply, said valve comprising a body having an air chamber communicating with the air supply and with the tank, a mixing chamber, a passage conn'ectingthe mixing chamber with the tank, avalve in the air chamber for controlling the flow of fluid through said passage, an opening forming a commu ication between the air chamber and the mi ing chamber, and a double actingvalve ,for closing said air supply communication or for closing said' communicating openin G STAVE BLUEMEL.
